They didn't send me a take down request.
They've only sent it to Twitter and Twitter didn't take the account down (yet). It looks like they pushed back and asked them to specify which tweets were infringing, leading to the removal of animated gif in some tweets 24-48h after they were sent.

Sorry for the inconvenience! See my comments above. Please let me know if you are still experiencing this issue. You can also just let me know the id you received and I can activate it for you.
Ok so I'm finally back on a computer. There are 158 webhooks registered. The ones for hipchat are mostly activated, but only a few for Slack are. Weird. Anyway, you should have received a link with the following format: http://replaylastgoal.com/hooks/activate?service=slack&id=ab...
Replace id with your id and that should work. Not sure what happened. Still investigating. Ping me on twitter @xdamman or gmail (same username) if you are still experiencing an issue when trying to activate your hook. I'll send a reminder to activate the hook for the ones that haven't been activated by tomorrow before the game.
Thanks for reporting. I'll fix this bug later today when I'm back at a computer.
More than 100 teams got the notifications during the game Belgium USA so it's working.
Both the IP of the server and the account are white listed.
Which gives me 40.000k lists to monitor (without counting that some people monitor the same list).
I would be more than happy to have this kind of scalability issue. Hopefully I'll make it to YC and have de facto preferred access to Twitter APIs. Fingers crossed :-)
